CHAIN CLASP.

Appllication led October 14, 1922. Serial 110.594,435.

To all w homc't may concern.'

Be it known that I, GEORGE F. EGKART, a citizen of the United States,residing at Norwood, in the county of Hamilton and State of Ohio, haveinvented certain new and useful Improvements in Chain Clasps, of whichthe following is. a specification.

My invention relates to'clasps which are particularly adapted fordetachably Vconnecting the ends of a chain or cable.

The objects of my invention are to pro, vide a simple, convenient7economical and easily opera-ted means for connecting and disconnectingthe ends of chains, cables and the like.

My invention consists in the combination and arrangement of parts asherein set forth and claimed.

ln the drawing:

Fig. 1 is a side elevation showing my invention in closed positionconnecting the ends of the chain; y

' l? ig. 2 is a side elevation showing the hook disconnected from thespring Aand in posi- 1' tion for inserting or removing it from the linkof the chain;

Fig. 3 is a similar view showing the,`

spring compressed against the eye of the hook to permit the clasp to bedisconnected from the other end of the chain;

Fig. le is a. plan view of Fig. 3; and

Eig. 5 is a cross Section on the line 5--5 of Fig.

ln the embodiment of my invention as illustrated and which shows thepreferred construction the clasp comprises a curved hook l having astraight projecting linger 2 on its free end and an eye 3 upon its otherend engaging eye 4 upon one end of the open link 5 having eye 6 andprojecting stem 7 on its other end.

@pen link '5 is adapted to be detachably connected other link thereof asmay be desired. Coil spring 10 is mounted upon open link 5 and when theclasp is in closed position yit engages fingerr 2 of curved hook 1 asshown in Fig. 1. Projecting stem 7 is preferably disposed at an angle tothe body of open link 5 gradually increasing in distance therefromtoward its free end for the purpose of more readily inserting link 8 ofthe chain. Curved hook l is adapted to be Vthe chain.

to end link 8 of chain 9 or anyv turbed except when removing the claspentirely from the chain. To connect the hook to the other end kof thechain compress spring 10 to the position shown in Fig. 2 so that finger2 is entirely free to be moved upon Vits pivot to the position shown bydotted lines in Fig. 2. Insert finger 2 through link ll as sho-wn inFig` 2 bringing it to the position shown in dotted lines in said figure,and then permitting springy 10 to expand to the position shown in Fig.l. This will result in effectually and eiciently detachably connectingthe ends of To disconnect the clasp from the chain simply reverse theoperation.

This device possesses the advantages of extreme simplicity andconvenience and quickness of operation and has no parts yvhich areliable to work loose and become ost.

Another advantage of the invention is that the device, can be operatedto connect or disconnect the yends of a chain without any tools.

My invention constitutes an emergency clasp'which is adapted for use forautomo bile tire chains. f

'What I claim as new and desire to secure by Letters Patent is:

l. Iny a clasp, a link having an eye in each end, a compressible coilspring thereon, a hook pivoted in one of said eyes and adapted to beretained in closed position by said coil spring when said spring isexpanded and adapted to beo-pened from said closed .position whensaidspring is compressed.

2. In a. clasp, an open link having a closed eye at one end andan openeye at the other end with a stem projectingtherefrom, aV

compressible coil spring around said link and a hook pivotally connectedto said closed eye and adapted to be held in closed position by seidcoil spring and adapted to beopened from a Closed position when saidspring is compressed.

3. In a clasp'` a link havingan open end 5 and a closed end, and a, hookpivotally connected to V'said Closed end and having a pro;

jecting end, a compressib'le coil Spring around said link andpwhenexpanded adapted to retain said clasp in closed position by ,engagingsaid projecting end and When Ycompressed adapted to disengage saidprojecting end `and permit said clasp to be
